Off-equilibrium scaling behaviors driven by time-dependent external fields in three-dimensional O(N) vector models
Andrea Pelissetto, Ettore Vicari
We consider the dynamical off-equilibrium behavior of the three-dimensional O vector model in the presence of a slowly-varying time-dependent spatially-uniform magnetic field…
Off-equilibrium scaling behaviors across first-order transitions
Haralambos Panagopoulos, Ettore Vicari
We study off-equilibrium behaviors at first-order transitions (FOTs) driven by a time dependence of the temperature across the transition point Tc, such as the linear behavior T(t)…
Quantum Ising chains with boundary fields
Massimo Campostrini, Andrea Pelissetto, Ettore Vicari
We present a detailed study of the finite one-dimensional quantum Ising chain in a transverse field in the presence of boundary magnetic fields coupled with the order-parameter spi…
Bose-Einstein condensation and critical behavior of two-component bosonic gases
Giacomo Ceccarelli, Jacopo Nespolo, Andrea Pelissetto +1
We study Bose-Einstein condensation (BEC) in three-dimensional two-component bosonic gases, characterizing the universal behaviors of the critical modes arising at the BEC transiti…
Three-dimensional antiferromagnetic CP(N-1) models
Francesco Delfino, Andrea Pelissetto, Ettore Vicari
We investigate the critical behavior of three-dimensional antiferromagnetic CP(N-1) [ACP(N-1)] models in cubic lattices, which are characterized by a global U(N) symmetry and a loc…
Quantum transitions driven by one-bond defects in quantum Ising rings
Massimo Campostrini, Andrea Pelissetto, Ettore Vicari
We investigate quantum scaling phenomena driven by lower-dimensional defects in quantum Ising-like models. We consider quantum Ising rings in the presence of a bond defect. In the…
